Answer:
21cm^2
Step-by-step explanation:
1/2 5 x 6 = 15
1/2 x 4 x 3 = 6
15+6 = 21cm^2
If you was working out a missing angle you would 1/2 the longest lines and add them up then add the shortest line
ie) 1/2 6 = 3
1/2 3 5 = 2.5
36+ 25 = 61 sq rt
= 7.81
Then find your multiplier 6/5 = 1.2 you take this multiply by 10
12 and half it = 6 x 7.810 = 46.86 = your angle for the larger triangle.
The smaller triangle missing angle is same method but you keep the multiplier without multiplying by 10 or halfling it, you need to half the 2 sides first then add them to the smaller side found doing Pythagoras and find you r multiplier large side/ second largest side = x then times x by the multiplier two sides halved and smaller side added. = 3 sq 4 sw = 9+16 = 25 sq = 5 large then + half 4 = 2 + 3
= 2.5+ 2 + 3 = 7.5
then 5/4 = 1.25
=1.25 x 10 = 12.5 then half it = 6.5 then multiply it by 7.5
=6.5 x 7.5 = 48.75 missing angle smaller triangle.
write any value that is a solution of inequality 2x+1≥11.
Answer:
x ≥ 5
Step-by-step explanation:
2x+1≥11
2x + 1 - 1 ≥ 11 - 1
2x ≥ 10
2x/2 ≥ 10/2
x ≥ 5
Any value of x that is greater than or equal to 5 will be a solution of the inequality 2x + 1 ≥ 11. ( x = 5, x = 6, x = 10, etc. )
What is the solution to the inequality?Given the inequality in the question:
2x + 1 ≥ 11
To find a value that is a solution of the inequality 2x + 1 ≥ 11, we need to find a number for x that makes the inequality true.
2x + 1 ≥ 11
Isolate the variable term by subtracting 1 from both sides of the inequality:
2x + 1 - 1 ≥ 11 - 1
2x ≥ 11 - 1
2x ≥ 10
Next, divide both sides by 2 to solve for x:
2x/2 ≥ 10/2
x ≥ 10/2
x ≥ 5
Therefore, the value that is a solution can be any number greater than or equal to 5.

Elena rolls two cubes
numbered 1 to 6. What is
the probability that she rolls
two numbers with a sum of
9?
Answer:
I thought it was 1/9
Step-by-step explanation:
favorable out comes are 4
and total out comes are 36
The probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happeing of the event.
We have:
Elena rolls two cubes numbered 1 to 6.
The total outcome = 6×6
As there are two cubes with each cubes numbered 1 to 6
Total number of favourable outcomes = 4
Which are (3, 6), (4, 5), (5, 4), and (6, 3)
Now the probability P will be:
[tex]\rm P = \frac{4}{36}[/tex]
[tex]\rm P = \frac{1}{9}[/tex]
Thus, the probability that she rolls two numbers with a sum of 9 is 1/9 if the Elena rolls two cubes numbered 1 to 6.

Answer:
32 degrees
Step-by-step explanation:
Because the triangle is isosceles, 2 of its angles must equal each other:
15x - 31 = 9x + 11
---> x = 7
Plug 7 into either 15x - 31 and 9x + 11:
15(7) - 31 = 74 degrees
and
9(7) + 11 = 74 degrees
Add them together, and you get 148 degrees.
Finally, subtract 180 from 148 to get 32 degrees for angle S.

This rectangle and right triangle have the same perimeter.
What is the difference in their areas?

2.0 square cm
2.0 square cm
3.6 square cm
3.6 square cm
4.8 square cm
4.8 square cm
Answer:
0.18 cm²
Step-by-step explanation:
Given that a rectangle and a triangle have same perimeter . The sides of them are ,
[tex]\begin{cases} Square = 4cm , 4cm , 3cm \ and \ 3cm .\\ Triangle = 4cm , 5.8cm \ and \ 4.2cm \end{cases}[/tex]
We know that area of rectangle is product of length and breadth.
[tex]\implies Area = length \times breadth \\\\\implies Area = 4cm \times 3cm\\\\\implies \red{ Area = 12cm^2}[/tex]
Also we know that the area of triange is half the product of base and height . So that ,
[tex]\implies Area = \dfrac{1}{2}\times 5.8cm \times 4.2 cm \\\\\implies \red{ Area = 12.18 cm^2 }[/tex]
Therefore the difference between them is ,
[tex]\implies D = A_1 - A_1 \\\\\implies D = 12.18cm^2-12cm^2 \\\\\implies \red{D = 0.18 cm^2}[/tex]

1. remote interior angles
2. interior angles
3. supplementary angles
4. exterior angles
Answer:
(Page 1):
1.) 150°
2.) 25°
3.) 120°
4.) 60°
(Page 2):
1.) 180 - (40 + 30) = 110°
2.) 180 - (33 + 92) = 55°
(Page 3 doesn't show questions all the way)
Step-by-step explanation:
(Page 1):
1.) ∠1 and ∠2 are Straight angles which make up 180° if added up together => 180° - 30° = ∠2
2.) ∠5 and ∠8 are Vertical angles which means they are congruent , => if ∠5 = 25 then so will ∠8.
3.) By the opposite side alternate interior angles theorem ∠6 is congruent to ∠3,
=> if ∠6 = 120, then ∠3 = 120
4.) if there is a set of an exterior angle and an interior angle, they both add up to 180°.
=> 180° - 120° = ∠4

You've flipped the coin 3 times, and it has come up heads once. The cumulative fraction of heads is currently 1/3. If you flip the coin once more time, will it land heads up to make the cumulative fraction 2/4?
Answer:
Maybe. Either 2/4 or 1/4.
Step-by-step explanation:
If you flip a coin 100 times, ABOUT 50 percent will be heads up. Therefore it's not unlikely it up land heads up 2 out of 4 times, but its not unlikely it will be heads down either.
JKL- RST with a scale factor of 1.5
What is tan
Answer:
Step-by-step explanation:
Short answer No They are not congruent. The scale factor would be 1 if they were. JL and RT should both be the same length (they are opposite angles marked with 2 quarter circles). They are not equal. So the scale factor is not 1.
To get from JKL to RST you must multiply every length of JKL by = 20 / 25 or 4/5. So 15 * 4/5 = 12 which works. 4/5 * 20 = 16 which also works.
The two triangles are similar.
